The acarological and palaeontological communities lost a rising star when Dr Ekaterina Alekseevna (Katya) Sidor- chuk passed away in a tragic accident while diving in the Maldives on 20 January 2019. Katya was a good colleague of many acarologists and much-loved friend of numerous collaborators. She was a highly-valued member of the editing team of Zootaxa, serving as a subject editor for () for several years; her excellent editorial contributions were greatly appreciated by many colleagues and friends. To honour Katya, her colleagues and friends of the acarological world dedicate here a special volume of Zootaxa in her memory. This memorial volume collects 28 papers on a variety of topics and taxa (both fossil and extant), including 11 papers on (Fan et al. 2019; Ghasemi-Moghadam et al. 2019; Hajiqanbar et al. 2019; Khaustov et al. 2019; Khaustov & Frolov 2019; Lindquist & Sidorchuk 2019; Porta et al. 2019; Seeman 2019; Sidorchuk et al. 2019; Xu et al. 2019; Zmudzinski et al. 2019); 1 paper on Astigmata (Klimov et al. 2019) and 13 papers on other Oribatida (Bayartogtokh & Shimano 2019; Behan-Pelletier & Ermilov 2019; Colloff 2019; Hagino & Shimano 2019; Liang et al. 2019; Liu & Zhang 2019; Niedbała et al. 2019; Norton & Ermilov 2019; Páez et al. 2019; Ren et al. 2019; Resch et al. 2019; Shimano & Aoki 2019; Zheng et al. 2019); 3 papers on (Joharchi & Trach 2019; Makarova 2019; Mašán & Babaeian 2019). These papers also include 1 new genus and 19 new species named after Katya. The life of Katya and her important contributions to acarology and palaeontology were already described in two biographic papers: one published in Acarologia (Lindquist & Norton 2019) and another in Palaeoentomology (Ras- nitsyn 2019). The latter also includes a list of 61 papers published by Katya and co-authors. This volume adds two more of her papers: one on a new species of Eatoniana () in the Eocene Baltic amber (Sidorchuk et al. 2019) and another on a new species of Podapolipus (Podapolipidae) parasitic on a gryllacridid cricket in Australia (Lindquist & Sidorchuk 2019). To supplement the excellent biographic data of Katya provided by Rasnitsyn (2019) and Lindquist & Norton (2019), I herein provide a list of patronyms in her honour as well as a list of new taxa named by her and co-authors.

Patronyms in honour of Ekaterina Alekseevna (Katya) Sidorchuk

Two genera (1 fossil and 1 extant) and 23 species (3 fossil and 20 extant) were named after Ekaterina Alekseevna (Katya) Sidorchuk. Except one genus and three species of insects, all others are . Among the 25 patronyms, 76% (19) are named in papers of this memorial volume. Of the 23 species-group patronyms, most (13) are after her family name (sidorchukae or sidortschukae), 7 are after her given name (ekaterinae) and 3 after her nick name (katyae). Makarova (2019) transliterated Katya’s family name as Sidortschuk because she thinks this is the correct one from Russian.

New taxa named by Ekaterina Alekseevna (Katya) Sidorchuk and co-authors

Katya and co-authors established four family-group names (all fossil), eight genus-group names (all fossil) and 38 species-group names (12 fossil); all of these are for mites. A new genus († Palaeonothrus Krivolutski & Sidorchuk, 2003) was proposed for † Palaeonothrus polytrichus Krivolutski & Sidorchuk, 2003 and † Palaeonothrus rotundatus Krivolutski & Sidorchuk, 2003 (Sarcoptiformes: Oribatida: ), but these were later considered by Sidorchuk & Rasnytsyn (2009) to be mis-identified parts of Ichneumonoidea (Insecta: Hymenoptera). These are thus not included in the following lists.
